ARM: mach-shmobile: r8a7779 and Marzen base support V2 Initial support for the r8a7779 SoC and the Marzen board (V2). Only SCIF ports and the TMU are supported at this point. To keep things simple only entity-mapped virt-to-phys mappings are supported. This forces drivers and other SoC glue code to make use of ioremap(). We cannot support early serial console due to virtual address space collisions with the ARM kernel. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This adds support for 4 power domains for I/O Devices together with code that can be used for CPU cores as well. The only out of the ordinary experience is the need for ioremap() of SYSC registers. Because of that we need to execute some init function before setting up the domains. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

extern void r8a7779_init_irq_extpin(int irlm);
ARM: shmobile: r8a7779: split r8a7779_init_irq_extpin() for DT r8a7779 INTC needs IRL pin mode settings to determine behavior of IRQ0 - IRQ3, and r8a7779_init_irq_extpin() is controlling it via irlm parameter. But this function registers renesas_intc_irqpin driver if irlm was set, and this value depends on platform. This is not good for DT.

ARM: shmobile: Marzen: move USB EHCI, OHCI, and PHY devices to R8A7779 code USB EHCI, OHCI, and common PHY are the SoC devices but are wrongly defined and registered in the Marzen board file. Move the data and code to their proper place in setup-r8a7779.c; while at it, we have to rename r8a7779_late_devices[] to r8a7779_standard_devices[] -- this seems legitimate since they are registered from r8a7779_add_standard_devices() anyway. Note that I'm deliberately changing the USB PHY platform device's 'id' field from (previously just omitted) 0 to -1 as the device is a single of its kind. Note also that the board and SoC code have to be in one patch to keep the code bisectable... The patch has been tested on the Marzen board.

ARM: mach-shmobile: r8a7779 SMP support V3 This patch contains r8a7779 SMP support V3 - now including CPU hotplug offine and online support. The r8a7779 power domain code is tied together with SMP glue code which allows us to control the power domains via CPU hotplug. At this point the kernel boots with the 4 Cortex-A9 cores in SMP mode and all CPU cores except CPU0 can be hotplugged. The code in platsmp.c is quite far from pretty, but it is kept like that intentionally to avoid creating layers of code that will go away in the near future anyway. The code needs to be updated when some per-SoC handling code will be added to the ARM architecture, see the following patch for more information: "[RFC PATCH 0/3] Per SoC descriptor" Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
